Participants are required to pledge to turn off the air conditioner on 7th October (suggested from 7pm to 7am the next morning). An air-conditioner with 1hp (see Note 1) consumes 0.8 to 1 kWh of electricity per hour, and emits 5.6kg of carbon dioxide (for 8hr of use per night). This amount takes 3 months for a mature tree to fully absorb. In another words, each participating family or university hostel resident may save at least 5.6kg of carbon dioxide emission during that night.It is a family decision to turn off the air-conditioner, we suggest to consult your family member first, and explain the purpose of the event. If you are a university hostel resident, please consult your roommate(s) as well.Note 1: To simplify, we conservatively assume each family to have only one 1hp air-conditioner. Many families have larger power air-conditioner, e.g. 1.5hp or 2hp, and one or more air-conditioners may be installed in one family.
